Austyn Crites (M.B.A. ’09) told reporters that the commotion started when he held up a sign that read “Republicans against Trump.”

A witness said he heard someone scream “This guy has a gun.” According to a Secret Service statement, an “unidentified individual” in the crowd shouted ‘gun,’ but the statement said no weapon was found.

Agents entered the crowd and detained Crites. Crites said he was relieved when the police broke up the crowd. He said he was kicked, punched, choked, and grabbed by the testicles.

"All of a sudden, because they couldn't grab the sign, or whatever happened, bam, I get tackled by all these people who were just, like, kicking me and grabbing me in the crotch and just, just beating the crap out of me," Crites told CNN affiliate KTNV. "And somebody yells something about a gun, and so that's when things really got out of hand."

Secret Service agents, police officers, and SWAT officers carrying assault rifles led Crites away from the crowd to a side room.

Crites was released from custody after the rally with no charges, CNN reported.

Trump returned to the stage minutes later. “Nobody said it was going to be easy but we will never be stopped,” he said. “We will never ever be stopped.”
